The Lowdown
G’day, Rusty here, and I’ve been staring at the charts for this next stretch, and honestly, it’s a pretty rare run we’ve got lined up. We’re looking at one spot, and one spot only, but it’s a cracker. The water is sitting at a warm 80°, which is pretty much bang on average for this time of year, so no surprises there.
The action kicks off on Saturday morning, September 5th, but the early call is a bit of a letdown. We’ve got a clean 6ft SSW swell rolling in at Lakey Pipe, but the wave comment flags it as marginal. The combined energy sits at 1249, so there’s moderate power there, but it just doesn’t seem to be coming together perfectly. By Saturday afternoon, the swell bumps up to 6ft from the SSW with a long 16-second period, energy jumps to 1685, but a cross wind messes the surface up a bit. Not a write-off, but not the good stuff yet.
Sunday morning, September 6th, is where it starts to get good. The swell holds at 6ft from the SSW, period a solid 14 seconds, and the wind is a light cross-off from the SSE. The water is glassy, the waves are clean, and the energy is at 1635. This is a proper session for the experienced crew. Sunday afternoon gets even better: the swell pushes to 7ft, the period stretches to a very long 17 seconds, and the energy jumps to 3261. It’s clean, cross-off, and powerful. This is one of the standouts.
The whole week from Monday the 7th through to Friday the 11th keeps pumping solid 7ft to 8ft SSW and SW swells, with periods mostly between 14 and 16 seconds. The wind is consistently cross-off, keeping the surface clean. The combined energy sits comfortably in the 1770 to 3504 range, so we’re talking moderate to strong wave energy. Crowds are often here, so you’ll have company, but for waves this good, it’s worth it.
The second week, from September 14th onwards, the swell backs off a touch to 5ft to 8ft, but the quality stays high. The real standout in the long-range is Sunday the 13th, where we see a 6ft SW swell with a very long 19-second period and a light cross-off breeze. The energy is 3074, and it’s clean. That’s a day for the reef to really shine, with those long lines peeling down the point. The following Wednesday, September 16th, also looks promising, with a 8ft SSW swell and 16-second period, but the wave comment notes it’s marginal, so keep an eye on the tide.
Overall, this is a solid 16-day run. The best bet is Sunday the 6th afternoon and Sunday the 13th morning for the cleanest, most powerful waves. With the swell over 5ft and up to 8ft, this is for intermediate to expert surfers. Beginners should stay out of the water on the bigger days.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
